Yeah I'll update the articles to link them all together. Thanks for the idea!

I'm not a comment guy honestly unless some portion of the code is difficult to understand.

Since here it's a basic setup where everything is pretty easy to understand by just reading the code I don't comment just for the sake of adding comments.
IMO a good function comment header should be enough. Commenting inside a function should only be done if the business logic is complicated and the developer can't understand at first glance.
